Whole House Fans are ideal for residential use in mild to moderate climates as a supplement to air conditioning. Our belt drive units have been engineered to offer a superior performance with a more stable motor mount that is stronger than typical tube-style bracing and virtually eliminates vibration alongside an automatic shutter in a powder-coated white finish to blend in seamlessly with your ceiling. Install as a joist-in or joist-out configuration and control the unit from anywhere in your home from your smart device. Whole House Fans offer an efficient way to reduce cooling costs by pulling fresh air in from the outside, expelling the warm air up into the attic, and pushing it out through the attic exhaust vents. Save on energy costs by taking advantage of the timer setting available only on Wi-Fi hub units, which will automatically turn off your unit after your desired time setting has been reached.

Free Wi-Fi app on smartphone controls all of the whole house fan functions.

Our Wi-Fi whole house fans are controlled using our free Wi-Fan app, which can be downloaded on any smart device. Control multiple fans independently, set the speed or place the fan on a timer, or turn the fan off without ever getting up to flip a switch.


Our whole house fan line features a shutter that opens and closes automatically with the fan's operation, making startup a breeze. In winter when the fan is not in use, the shutter maintains a 95%+ air closure to keep heated air in your living areas and out of your attic space.

Whole house fans pull cool air from open windows and doors throughout the house and push stale, warm air upwards to escape through your attic, making them a perfect alternative to an air conditioner in moderate climates. Feel instantly refreshed with this energy-saving cooling measure!
